Improved table-leaf support



UNITED STATES PATENT OFFICE l ASA FORREST, OF MOINGONA, IOWA, ASSIGNORTO HIMSELF AND O. L.

FRENCH, OF SAME PLACE.

IMPROV'ED TABLE-LEAF SUPPORT.

Specification forming part of Letters Patent No. 102,528, dated May 3,1870.

To all whom it may concern.-

Be it known that I, ASA FORREST, of Moingona, in the county of Boone andState of Iowa, have invented a new and useful Improvement in Tables andI do hereby declare that the following is a full, clear, and exactdescription thereof, which will enable others skilled in the art tomakeand use the same, reference being had to the accompanying drawings,forming part of this specification.

` above the right line between the end pivots and retain the position byreason of the tendency of the vweight of the leaf to prevent the bracesassuming the rightA line, which they must do before folding down. Thetendency of the weight to force the joint upward and the two parts tofold down the other way is counteracted by the arrangement of the arms,so that the joint will strike the under side of the table.

The invention also consists in the application of a safety-latch tofacilitate the adjustment of the braces and to prevent them from beinginadvertently thrown down.

Figurev l is a transverse sectional elevation of a table with the leafthrown down, and Fig. 2 is a similar section with the leaf in theelevated position.

Similar letters of reference indicate corresponding parts.

A is the top of the table; B, the leaf, and C the side rail of the topframe of the table.

Dis one arm of the brace, and E the other. They are jointed together atF. D is pivoted to the under edge of the rail G, and E is pivoted to theunder sideA of the leaf. These arms are so arranged as to length thatwhenthe leaf or fall is raised slightly above Pthe horizontal line thejoint F will come to aright line between the joints of the arms with therail and the leaf, and will admit of the said joint being raised abovethe said right line, so that the weight of the leaf or other weightthereon will prevent the folding down of the brace, and will cause it tofold up the other way. This, however, is prevented by the contact of thejoint with the under side of the leaf, the arrangement being such thatthe joint will strike the table as soon as it passes the said line. Whenthe leaf is to be put down' the brace is bent back below the right linebetween the pivots at the ends, and then it readily folds down to theposition represented in Fig. 2. This arrangement constitutes a verystrong brace, much more capable and serviceable than the ordinary arms,which swing out from slots in the rails C in horizontal planes. ln orderthe more readily to adjust the brace to the holding position, and tosecure itagainst being inadvertently thrown down, I have provided asliding safety-latch, H, whereon is a vertical plate with an inclinedslot, I, (shown dotted in Fig. 2,) which, when slid inward from theouter edge of the-fall, will engage a pin, K, on the side of the shortarm E ot' the brace, so as to force it up to the required position andhold it there. The same arrangement also throws the arm down when drawnback,- aswill be clearly seen by inspection of the drawings. Thesebraces may be made either of metal, as shown in drawings, or of wood,joined together and to the feet and frame of the table with metal hingesor otherwise.

l Having thus described my invention, I claim as new and desire tosecure by Letters Patent- Y l. The jointed brace D E, when permanentlyattached to the fall-leaf at one end and to the frame of the table atthe other, and having its two arms of such proportional length as tofold up in the manner described.

2. The combination, with the leaf and brace,

of the safety-catch H, arranged and operating substantially asspecified.
